Some declarations in compressonator.h are not defined in Compressonator_xx.lib

Hello,

I downloaded CompressonatorSDK_x64_4.3.206.exe and setup a project with include/compressonator.h and lib/VS2019/x64/Compressonator_MD.lib to run the examples/sdk_example1/SDK_example.cpp. Everything worked and I compressed ruby.dds into ruby.dds but BC7 👌.

I tried to follow the comment in the example

compressonator/examples/sdk_example1/sdk_example1.cpp

Lines 37 to 38 in 38081a0

// A newer DDS loader utility is provided in V3.2 SDK : CMP_LoadTexture and CMP_SaveTexture, These use the MipMap structure
// to hold the image buffers used for processing.

Added this line to test if it will build auto * func_ptr = CMP_LoadTexture

It failed with the error main.cpp.obj : error LNK2019: unresolved external symbol CMP_LoadTexture referenced in function main

Did a quick test and only the functions CMP_Format2FourCC, CMP_IsCompressedFormat, CMP_IsFloatFormat are defined in this block of declerations

compressonator/cmp_compressonatorlib/compressonator.h

Lines 982 to 997 in 38081a0

This seemed like an issue on your side, hence this report.

Additionally:

  • Is there a utility in the SDK that can load various image formats besides dds (especially png/jpg/hdr)?
  • How can I run CMP_ConvertTexture & CMP_ConvertMipTexture on the GPU? The SDK section of the documentation does not mention this.

Same issue with the missing symbols in the .lib.
